Stuff her in a cake

A little-known fact about you is that you're a whiz with beauty secrets. Even despite Hannah's squirming, you manage to do her hair, give her a pouty set of lips, come-hither eyes, and some sparkly body glitter. After peeling off her underwear, you even manage to wax everything below her navel. She'd look like a heartthrob diva if it weren't for her complete lack of breasts.

"Omigod, you look adorbs," you say, pinning her arms behind her back and pointing her at Raider. "What do you think, Raider?"

"They're going to love her," he says. "She just needs a few finishing touches."

Before she can protest, he's slapped a pair of bunny ears on her. The two of you then get to work giving her a pair of whipped-cream breasts, a whipped-cream crotch guard, and a little whipped-cream cottontail.

"There!" you say, finishing off with a couple of cherry nipples. "That guy isn't going to think of you as a little girl anymore when he sees you like this! Now, let's get you into the cake!"

"You'll never get me to pop out of it!" she says. "I have my womanly dignity!"

"Fine," you shrug. "I guess they'll just discover you inside when they start eating it."

Hannah swallows. She hadn't considered that.

"Meanwhile, we'll see how much that whipped cream holds together by the time they get to you. Mm'kay?"

You stuff the girl into a big, chocolate cake as she furiously tries to bargain with you, then deliver it to the party.
